主要利用 H(t,s,t0)型函数和广义 Riccati 变换技巧,给出了一类二阶非线性时标动态方程(p(t)ψ(x(t))xΔ(t))Δ+f(t,x(σ(t)))=0新的Kamenev型振动准则。
By using functions of the form H(t,s,t0 )and a generalized Riccati transformation technique, new Kamenev-type oscillation criteria are established for second-order nonlinear dynamic equations on time scales of the form (p(t)ψ(x(t))xΔ(t))Δ+f(t,x(σ(t)))=0.
